7 Claims, 4 Drawing Figures v E DEVICE FOR GUIDING CABLES ON CYCLES The invention relates to a device for guiding cables on cycles.

Devices for guiding cables for changing the speed with a gear shift are already known. These devices consist of a collar provided with an eyelet which is tightened around one of the cylindrical tubes of the frame with the aid of a screw.

It is, however, difficult to maintain these devices in position because of the traction forces exerted on the cable, and quite often the collar slides on the tube of the frame which results in the control of the gear shift of the rear wheel of the cycle or the device for changing the chain wheel of the crank-gear going out of order.

Likewise, for guiding traction cables on bicycles, use has been made of sheaths which are placed between two fixed stops constituted by collars and which enable the cable to be guided when it is desired to change its direction.

However, the fitting of a cable in such a sheath is relatively complicated; it requires a precise adjustment of the position of the stops and in addition, the control of a gear shift by means of a cable passing through such a sheath is inaccurate, since, when a traction force is exerted on the cable, the cable exerts a lateral force on the sheath, so that the loop which the sheath forms tends to reduce its length, which leads to the control of the gear shift going out of order.

The object of the present invention is in particular to overcome these disadvantages and relates to this end to a device for guiding cables on cycles, characterized in that it consists of a collar provided with guides for the passage of cables, the collar having two obliquely opposite flanks, and the cable guides being formd by folding over the tongues provided on the collar.

According to another characteristic feature of the invention, the collar has two opposite support edges virtually equidistant from the oblique flanks.

The invention is illustrated by way of non-limitative example in the accompanying drawings in which:

FIG. 1 is a perspective schematic view of the device,

H0. 2 is a lateral view of the device, fitted to the base of a frame of a cycle,

HO. 3 is a front view of the HO. 2,

FIG. 4 is a plan view of the device.

The invention therefore relates to the construction of a device consisting of a guide collar which can be fitted rapidly andthe position of which is rigorously defined with respect to the frame of the cycle.

In addition, this device, whose position is unalterable, enables the traction cables to be fitted rapidly, the control of the gear shifts unalterable.

On the adjoining Figures, such a device has been illustrated, which has the form of a metallic collar, of generally oblong form, having opposed portions of which the two bent ends 1 and 2 have facing flanks angularly or obliquely disposed with respect to each other. The collar is split at the distal end of one of said oppositely facing flanks.

The collar comprises tongues 3, 4 and 5 which are bent towards the exterior and which delimit the grooves 3,, 4, and 5, of which the bottom is convex so with the aid of these cables being as to enable the'direction of the cable to be changed without forming any sharp angle.

Thus, in the example illustrated, the groove 5 with a convex bottom allows the passage of the traction cable connecting the gear shift of the back wheel to the control handle, while the grooves 3 and 4 allow the passage of the traction cable connecting a control handle to the device for changing the chain wheel of the crank-gear.

This device, on account of its construction, can be fitted in a way (see FIG. 2) such thatthe oblique part 1 of the collar fits around a tube 6 of the frame, while the bent part 2 fits around the tube 7 of the same frame.

Likewise, this collar has two support edges 8 and 9, which are opposite one another and face away from the grooves 3,, 4,, and 5,. They are virtually equidistant from the oblique flanks l and 2, so as to bear on the upper edge of the crank-gear case 10.

It is thus seen that the groove 5, formed by folding the tongue 5 enables a cable to be fitted first of all parallel to the tube 6, then virtually parallel to the branch 11 of the rear fork, toward the gear shift. Likewise, the grooves 3, and 4, of the tongues 3 and 4 allow a cable to be fitted first of all parallel to the tube 6, and then passing over the tube 7, to arrive at the mechanism for changing the chain wheel of the crank-gear.

Tightening the device in the position illustrated on H6. 2 is effected with the aid of a screw and a nut placed across orifices provided in the ends 12 and 13 of the collar 1, these ends 12 and 13 being situated in the curved area 1 of the collar.

The positioning of the device is therefore automatic, since, by tightening the ends 12 and 13 with the aid of a screw, the collar tends to slide on the tubes 6 and 7 so that the edges 8 and 9 come to bear firmly on the upper edge of the crank-gear case 10.

It is then noted that the traction forces exerted on the cable cannot cause a displacement of the collar, since the latter is applied, on one hand in the case 10, and on the other against the divergent edges formed by the tubes 6 and 7.

The device can therefore be fitted simply, precisely, and in a manner so that it does not go out of order and enables the cables to be fitted rapidly by introducing them into one of the grooves 3,, 4, or 5,, the cable being then able to slide freely in the grooves without it going out of order.

It is obvious that the invention is not limited to the examples of its application herein above described and illustrated and that on the basis of which other modes and other forms of application can be envisaged without departing from the scope of the invention.
